[PHP] Weird virtual() behavior for nested require()

[Paul Cantrell]

I'm getting a weird behavior when virtual() calls another page that 
uses a require().  The behavior seems contrary to the docs for virtual.

Consider these four files:
    ------ foo.php ------
    This is foo.
    <?php virtual('subdir/bar.php'); ?>
    ------ foo.shtml ------
    This is foo.
    <!--#include virtual="subdir/bar.php"-->
    ------ subdir/bar.php ------
    This is bar.
    <?php require('./baz.php'); ?>
    ------ subdir/baz.php ------
    This is baz.
According to the docs, virtual() handles the argument as an Apache 
subrequest -- in other words, it should be equivalent to an SSI 
include.  But it's not.  As I would expect, foo.shtml produces this:

    This is foo. This is bar. This is baz.
Here's what I get from foo.php:
    This is foo. This is bar.
    Warning: main(./baz.php): failed to open stream: No such file or 
directory in
    /blah/blah/blah/subdir/bar.php on line 2

    Fatal error: main(): Failed opening required './baz.php' 
(include_path='.:/usr/local/lib/php')
    in /blah/blah/blah/subdir/bar.php on line 2

Oddly, it works if bar.php says require('baz.php') instead of 
require('./baz.php').  That smells really bad.  Is this a bug, or am I 
missing something?

Cheers,
Paul
